Ryan Reynolds undergoes 'potentially life-saving' surgery, records it on camera

Hollywood actor Ryan Reynolds had an "extremely subtle polyp" removed in a "potentially life-saving" colonoscopy. The actor underwent the procedure with his friend Rob McElhenney on camera in a new YouTube video to raise awareness on colon cancer. "This was potentially life-saving for you, I'm not kidding, I'm not being overly dramatic," the doctor told Ryan.
